The visit was fine and the people were nice as usual. However, a small thing. I think it is confusing with the 20 minutes intervals you schedule and the time sent by email to confirm, i.e. I wanted a 9:30 appointment and confirmed it but when I got there it was for 9:40. Perhaps the computer and schedulers should get in sync. However, I will know better next time and it did not spoil the visit.
